#response_parameters ⇒ Hash<String,String>

A key-value map specifying response parameters that are passed to
the method response from the back end. The key is a method response
header parameter name and the mapped value is an integration
response header value, a static value enclosed within a pair of
single quotes, or a JSON expression from the integration response
body. The mapping key must match the pattern of
method.response.header.\{name\}, where name is a valid and
unique header name. The mapped non-static value must match the
pattern of integration.response.header.\{name\} or
integration.response.body.\{JSON-expression\}, where name must
be a valid and unique response header name and JSON-expression a
valid JSON expression without the $ prefix.
